Tracing Early Migratory Neurons in the Developing Nose Using Contactin-2 (Cntn2) CreERT2. [PDF]
GenesisABSTRACT Neuronal migration during embryonic development is a fundamental process. In the developing nose of rodents, neurons that form during early neurogenic waves in the olfactory placode leave this structure to migrate toward or into the developing brain as part of the migratory mass.

Anatomy, histochemistry and immunohistochemistry of the olfactory subsystems in mice
Frontiers in Neuroanatomy, 2014 The four regions of the murine nasal cavity featuring olfactory neurons were studied anatomically and by labelling with lectins and relevant antibodies with a view to establishing criteria for the identification of olfactory subsystems that are readily ...

Evolutionary patterns and selective pressures of odorant/pheromone receptor gene families in teleost fishes. [PDF]
PLoS ONE, 2008 BACKGROUND: Teleost fishes do not have a vomeronasal organ (VNO), and their vomeronasal receptors (V1Rs, V2Rs) are expressed in the main olfactory epithelium (MOE), as are odorant receptors (ORs) and trace amine-associated receptors (TAARs).

Frontiers in Cellular Neuroscience, 2023 Vomeronasal sensory neurons (VSNs) recognize pheromonal and kairomonal semiochemicals in the lumen of the vomeronasal organ. VSNs send their axons along the vomeronasal nerve (VN) into multiple glomeruli of the accessory olfactory bulb (AOB) and form ...

A transcriptomic reevaluation of the accessory olfactory organ in Bichir (Polypterus senegalus)
Zoological Letters, 2022 Fish possess one olfactory organ called the olfactory epithelium (OE), by which various chemical substances are detected. On the other hand, tetrapods possess two independent olfactory organs called the main olfactory epithelium (MOE) and vomeronasal ...

Role of SoxE transcription factors in development and disease
Developmental Dynamics, EarlyView.Abstract Sox8, Sox9, and Sox10 arose by multiple rounds of genome duplications from a single SoxE gene in ancestral vertebrates. In this review, we will briefly discuss the molecular structure and function of SoxE transcription factors and their evolutionary origin. We will then discuss their expression, function, and developmental disorders.

Journal of Anatomy, EarlyView.Lungfish possess a lamellar OE and a primitive VNO called as a recess epithelium (RecE). Among the lungfish V2Rs expressed in both the lamellar OE and the RecE in small individuals, some became restricted to the RecE in large individuals. These results suggest functional separation between the lamellar OE and the RecE is still incomplete in juveniles ...

PLoS ONE, 2009 The vomeronasal system (VNS) mediates pheromonal communication in mammals. From the vomeronasal organ, two populations of sensory neurons, expressing either Galphai2 or Galphao proteins, send projections that end in glomeruli distributed either at the ...
